Description Bernard Cafarelli 2020-04-02 09:25:27 UTC

Running full neutron tempest plugin tests, I see in l3-agent.log errors on SIGHUP for at least keepalived and radvd after:
Running command (rootwrap daemon): ['radvd-kill', 'HUP', '712810'] execute_rootwrap_daemon /usr/lib/python3.6/site-packages/neutron/agent/linux/utils.py:103
Running command (rootwrap daemon): ['keepalived-kill', 'HUP', '402009'] execute_rootwrap_daemon /usr/lib/python3.6/site-packages/neutron/agent/linux/utils.py:103

And then log that the process should not have died

Version: OSP 16 RHOS_TRUNK-16.0-RHEL-8-20200324.n.0 (with tripleo-systemd-wrapper)


Reason is same as bug #1814616 with the wrapper SIGHUP will not be sent to correct process but bash (which will stop process and container)

Comment 1 Bernard Cafarelli 2020-04-02 09:26:45 UTC

Suggested fix in master to add exec to all sidecar wrappers

Comment 2 Bernard Cafarelli 2020-04-07 08:18:41 UTC

Master patch merged upstream, train backport in progress
